WILLIAM HENRY LINCI-I, OF BELLAIRE, OHIO.

WINDOW-SHADE AIPPLIANCE.

Application filed July 24, 1919.

To all whom it may concern:

Be it known that 1, WILLIAM H. LINOH, a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Window Shade Apipliances, of which the following is a speci cation.

This invention relates to improvements in window shade appliances of the type or character employed in raising or lowering the shade bodily to permit entrance of light and air at any desired point above or below the window shade.

The object of my invention is the provision of an appliance of this character which will occupy a comparatively small space and present an attractive and ornamental appearance, which can be easily adjusted to any desired position with reference to the window; which will possess merit in point of simplicity, durability and cheapness of construction and which generally, all things considered, will prove highly eflicient and practical.

With these purposes in View my invention consists of a window shade appliance embodying novel details of construction and arrangement of parts substantially as shown, described and claimed herein, it being understood that I reserve the right to make such changes in the construction as fall within the scope of the claim.

I have shown in the accompanying drawings a structure embodying the most efficient means I have so far devised for the carrying out of my invention, and for a more complete understanding of the improvements attention is directed to said drawings, in which:

Figure 1 is a perspective View of a portion of a window frame with my improve ments applied thereto;

Fig. 2 is a sectional view taken on the line 22 of Fig. 1;

Fig. 3 is a sectional view taken on the line 33 of Fig. 2, and

Fig. 4; is a sectional view taken on the line 41-41 of Fig. l.

In the drawings-the numeral 1 deslgnates a window frame or casing and 2 designates the upper sash which may be of any desired construction and in connection with which my invention is employed.

Upon the inner face of the casing and extending vertically thereof is secured a chan- Specification of Letters Patent.

nel or guide plate 3, which has mounted therein a foot 1 formed on the shade bracket 5, said bracket having a bearing 6 for the usual removable journal of the shade and to iaid bracket is secured at 7 one end of the The bar 8 extends entirely across the easing and window and is formed with an angled end 9 provided intermediately with an opening 10 providing the bearing for the other journal of the shade, while secured to its outer end is a guiding rod 11 which 1s adjustable vertically in the slotted tube 12. The tube 12 extends any desired length of the casing and is secured at its upper end to the casing by the bracket 13, while its lower end rests on a hollow rectangular casing 14: secured by its cars 15 to the casing, said rod 11 passing through the tube 12 and being held in any desired vertical adjustment with reference to the tube by means of the spring-actuated friction clamp 16, as most clearly seen in Fig. 2. As illustrated in Fig. 2, a coil spring is mounted on the lower end portion of the rod and is confined between the locking arms of the clamp 16 so as to normally press said locking arms into engagement with the rod.

The manner of operating my improvement will be readily understood from the description taken in connection with the drawings, and it will at once be apparent that the shade, which is of the ordinary construction and for the purpose of clearness of illustration of my improvement is not shown, is supported in the bearing 6 of the bracket 5 and in the bearing 10 of the angled end 9 of the bar 8. When found necessary or desirable to adjust the shade vertically with reference to the window, it is simply necessary by finger pressure upon the friction clamp 16 to release contact thereof with the rod 11 which will instantly permit the rod to be moved in the tube 12 carrying with it the bar 8 and bracket 5, and in consequence carrying the shade mounted upon said rod and bracket.

It will thus be seen that any desired adjustment of the rod with reference to the window may be obtained to allow for the entrance of light and air and at the same time to cause the shade to occupy the proper position with reference to the window, according to the desire of the user.

It will also be apparent that the device is composed of few parts to insure simplicity,

durability and cheapness of production and to generally produce an efficient and practical device of this character.

Having thus described the invention, What is claimed is A Window shade support including a vertically arranged slotted tube having its upper end attached to a Window frame, a hollow rectangular casing secured to the WindoW frame and supporting the lower 'end of said tube, a vertical rod slidably arranged in said tube, a pair of locking arms arranged in said rectangular casing and having open- 1ngs receivlng the said rod, a coil sprlng surrounding said rod and confined between said 15 connected to said transverse rod, and a guide 20 for the second-named bracket.

In testimony whereof I affix my signature.

WILLIAM HENRY LINOH. [1 8.
